The input impedance on the microphone inputs (in microphone mode) is typically 6kΩ. The audio input is

designed for use with inputs of between 1 μA and 10 μA at 94 dB SPL. If the biasing resistors are set to 1 kΩ, this

implies a microphone with sensitivity in the range -40 dBV to -60 dBV.

2.5.1 Speaker Output

The speaker output is capable of driving loads with a minimum impedance of 16Ω directly.

BTM510 FCC and Industry Canada Statements

The Final Equipment user manual must show the following statements:

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This

device may not cause harmful interference, and (2) this device must accept any interference received, including

interference that may cause undesired operation.

Changes or modifications not expressly approved by the party responsible for compliance could void the user’s

authority to operate the equipment.

To comply with the FCC RF exposure compliance requirements, this device and its antenna must not be co-

located or operating to conjunction with any other antenna or transmitter.

3.1.1 Considerations for OEM integration:

This module has a limited modular approval. Approval with any other antenna configuration or layout other

than that approved will necessitate additional radiated emission testing to be performed.

To inherit the modular approval, the antennas for this transmitter must be installed to provide a separation

distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any

other antenna or transmitter.

This module was approved with the following antenna:

RF Solutions: ANT-24G-WHJ-SMA 0 dBi

Operation of this module with any other antenna will require additional testing to be performed.

Co-location with other radio transmitting devices operating concurrently in the same band will require

additional testing and certification.

Designers should note the distinction that the FCC makes regarding portable and mobile devices. Mobile devices

are defined as products that are not used closer than 20cm to the human body, whereas portable devices can be

used closer that 20cm to the body. A device may be used in portable exposure conditions with no restrictions on

host platforms when the averaged output power is less than the low power threshold for an uncontrolled

environment ≤ 60/f (GHz) i.e. 25 mW for a 2.4 Ghz device. The Maximum Power Exposure for the BTM510 has

been evaluated and found to comply with the low power threshold for an uncontrolled environment.

Refer to FCC document KDB 447498 for more information on RF exposure procedures and equipment

authorization policies for mobile and portable devices.

3.1.2 FCC Labelling Requirement

If the FCC ID is not visible when the module is installed inside another device, then the outside of the device into

which the module is installed must also display a label referring to the enclosed module. This exterior label can
